由于中小水库合拢方面的资料比较少，在实际合拢过程中，可能会遇到围堰漏水问题，如事先考虑不周就会措手不及，不但造成经济损失，而且还会延误工期。对此，笔者在实践过程中总结出以下点滴经验。我们知道，合征前必须要打好围堰。围堰的位置一般选择在河道上游铺盖以外或边 Due to the small number of small and medium-sized reservoirs in the process of closure, leakage of cofferdams may be encountered in the process of actual closure. If they are not considered in advance, they will be caught unprepared, which will not only cause economic losses but also delay the construction period. In this regard, the author summed up the following bit of experience in the practice process. We know that we must lay the cofferdam before the syndrome.
